As I was flying home last night and downloading tweets before takeoff, I found out some amazing news. Ugh, not the time to have intermittent internet access! But eventually I got home, did the reading and confirmed the news.<\/p>\n
Oracle RAC 11gR2 (11.2.0.2) is now supported by Oracle under VMware<\/strong>.<\/p>\n You can read the updated My Oracle Support (MOS) announcement yourself in note 249212.1<\/a> which now states:<\/p>\n As I was flying home last night and downloading tweets before takeoff, I found out some amazing news.

RAC supported on VMware<\/span> \nNOTE: Oracle has not certified any of its products on VMware.\nFor Oracle RAC, Oracle will only accept Service Requests as described in this note on\nOracle RAC 11.2.0.2 and later releases.\n<\/span>\n<\/pre>\n\n(Remember: Certified is different than Supported<\/a> . Oracle doesn't certify hardware that isn't Oracle's own )<\/span>\n<\/span>\n<\/pre>\n\nThis is simply fantastic news. I talked to an petroleum company in Houston earlier this year<\/a> who wanted to virtualize their Oracle EBS system and move platforms from Sun Solaris to x86 architecture. Their big concern was that they were using 8 SPARC Processors and they knew that 8 x86 CPUs is the limit for a virtual machine under VMware vSphere 4.1. We discussed various steps they could take to ensure their environment would thrive under this limitation, but now it's a non-issue. In the event they need more computing power, they can implement Oracle RAC under vSphere and start up another RAC instance as necessary. <\/span><\/span>\n<\/pre>\n\nI do need to point out that as of this moment, 11.2.0.2 database is not certified or supported with Oracle Application (Oracle EBS) 11i or R12. These certifications usually come out a few months after the initial database announcement (which was Sept 10th for 11.2.0.2). If you check out the blog of Steven Chan (a Senior Director in Oracle's Applications Technology Group - the group responsible for the Oracle E-Business Suite technology stack) and specifically these comments<\/a> , you'll see that Steven wrote:<\/span><\/span>\n<\/pre>\n\n\nWe haven't certified 11.2.0.2 with Oracle E-Business Suite Release\n11i yet. This project is underway now. 11.2.0.1 is the latest\ncertified database release for the E-Business Suite.<\/span>
Oracle's Revenue Recognition rules prohibit us from discussing
certification and release dates, but you're welcome to monitor or
subscribe to this blog for updates, which I'll post as soon as soon as
they're available.
<\/span><\/span><\/span>\n<\/pre>\n\n
So 11.2.0.2 database certification with EBS 11i and R12 is coming.My main client doesn't use RAC (our business can survive the downtime associated with a HA event and we aren't near the 8 CPU limitation of VMware vSphere 4.1), but knowing its an option can only give upper management even more confidence that virtualizing our entire Oracle environment under VMware vSphere was the right thing to do.

<\/span>\n<\/pre>\n\nFor those wanting more information on Oracle RAC under VMware vSphere, I'd suggest watching this<\/a> Oracle virtualization webcast put on by Embarcadero and VMware a few weeks ago. I'd also highly recommend following VirtualTodd<\/a> on Twitter. Todd Muirhead was at Oracle OpenWorld in the VMware booth and presented some very interesting performance data from running RAC under VMware. I can't find a link to the presentation, but you can follow Todd's postings and perhaps find his testing results at his blog on the VMware communities site<\/a> .
<\/span><\/span>\n<\/pre>\n\nThink of the possibilities of combined Oracle RAC and VMware vSphere:
<\/span><\/span>\n<\/pre>\n\no Multiple RAC nodes on different vSphere hosts means no database downtime during a hardware failure.
<\/span><\/span>\n<\/pre>\n\no Combining multiple RAC databases on same vSphere host to consolidate workloads but still segregate environments
<\/span><\/span>\n<\/pre>\n\no Much faster provisioning of new RAC nodes with vSphere virtual machine cloning and VMware VAAI (vStorage APIs for Array integration<\/em>)<\/span>
o ... and many more I still need to wrap my head around<\/span>
